MBD WORST TO DEAL WITH

MBD are the worst company to deal with, MTN has *******ly charged me for itemised billing for a account that was closed and paid up. MTN handed me over to MBD. The more I try to sort it out the more phoned calls get dropped in my ear, consultants say I must just pay. really no training is provided to your MBD consultants. THEY NEVER MAKE NOTES OF WHAT WAS DISCCUSED. PLEASE PULL ALL PHONE LOGS AND SEE.

once again can someone in management please contact me regarding this. I will not pay an amount that I do not owe.
